Having worked as a language teacher for years, I know that a lot of students just hate grammar. (Of course I love it! ;-) Since I started to try to learn Japanese I have been looking for some simple way to get a grip of the system of the Japanese grammar, and here it is!!
I am sure there is a lot more to learn, but for me this was a great introduction.
So: Forget your fears and hate, and give this a try!
